I purchased the CS4 to replace my OEM Michelin's on a 2009 Buick Enclave. I was disappointed the Michelin had only given me 75,000 Km but that is 25% better than the CS4 is about to yield. I am at 52,000 km and have only 4/32 of thread on tire remaining. A trip to my tire dealer was frustrating in the i was told there was no wear warranty on this tire yet competitors in Canada (Canadian Tire) and US (Pep Boys) all post 95,000 km or 60,000 mile warranties. I was told that my tire was a performance rated tire. Yet everything i read of the CS4 is that it is a "luxury premium touring tire". I am not pleased and it is doubtful after spending $250 / tire that i will ever place another Cooper tire on my vehicles.
